Moni nonse, ndine mkonzi.Pafupifupi muzinthu zonse zamagetsi ndi zamagetsi, zolumikizira bolodi-to-board zakhala chinthu chofunikira cholumikizira zigawo zosiyanasiyana.Kukhalapo kwa cholumikizira sikuli kokha kwa disassembly ndi kugwirizana, komanso chonyamulira chopereka chamakono ndi chizindikiro kwa mankhwala.
Pogwiritsa ntchito zolumikizira, ambiri opanga makina amagetsi akhala ndi zochitika zofanana: kugwiritsa ntchito zolumikizira zotsika mtengo, ndiyeno kulipira mtengo wapamwamba, ngakhale kudandaula.Kusankhidwa kolakwika ndi kugwiritsa ntchito zolumikizira kungayambitse kulephera kwadongosolo, kukumbukira kwazinthu, milandu yamabizinesi, kuwonongeka kwa board board, kukonzanso ndi kukonza, komwe kungayambitse kutayika kwa malonda ndi makasitomala.Choncho, popanga zinthu zamagetsi, muyenera kusankha cholumikizira choyenera cha chipangizo chamagetsi.Kupanda kutero, momwe cholumikizira chaching'ono cha board-to-board chimapangitsa kuti dongosolo lonse lisagwire ntchito lidzamva kusweka kwambiri.

Anthu akasankha cholumikizira, choyamba amaganizira za kuwongolera mtengo.Zina ndizopamwamba kwambiri, kukhazikika kwapamwamba, ndi mawonekedwe apangidwe a cholumikizira chokha.Pofuna kupewa opanga zamagetsi kuti asachepetse kufunikira kwa zolumikizira pakupanga mapangidwe, chifukwa cha zotayika zazing'ono ndi zotayika zazikulu, opanga ma board-to-board cholumikizira amapereka malingaliro kwa aliyense:
Choyamba: lingaliro la double pole design.Pagulu la cholumikizira cha ERNI, lingaliro la mapangidwe amitundu iwiri limakhala logwirizana ponseponse.Kulankhula momveka bwino, mapangidwe amitundu iwiri amatha kufotokozedwa ngati "mbalame ziwiri ndi mwala umodzi".Mapangidwe okhathamiritsa ma terminal kuti agwirizane ndi kutumizira ma siginecha othamanga kwambiri, kupereka kulolerana kwapamwamba.Pankhani ya inductance, capacitance, impedance, etc., mawonekedwe opangira mipiringidzo iwiri ndi yaying'ono kuposa mawonekedwe amtundu wa bokosi kuti agwiritse ntchito mothamanga kwambiri ndipo amakometsedwa kuti akwaniritse kulephera kocheperako.Mapangidwe apawiri-pole amalola zolumikizira zingapo kukhala pa bolodi lozungulira limodzi popanda plugging kapena vuto lalifupi lozungulira, ndipo palibe chifukwa cha kuchuluka kwa ma sign pa cholumikizira chimodzi.Njira yosavuta ya mizati iwiri imatha kupulumutsa malo, kupangitsa cholumikizira kukhala chaching'ono, ndikupangitsa kuti zidziwitso za ma solder zizindikire.Mwachitsanzo, ikani 12 pa bolodi.Zimachepetsanso ndalama zogwirira ntchito.Mapulogalamu othandiza monga zida zogwiritsira ntchito ma telecommunication terminal, etc.
Chachiwiri: Mapangidwe okwera pamwamba okhala ndi mphamvu zosungira kwambiri.Pazinthu za SMT, amakhulupirira kuti mphamvu zogwira pa bolodi ndizosauka.Kodi mphamvu yosungira ya PCB yoyimitsa pamwamba pa phiri ndi yotsika kuposa ya kutha kwa dzenje?Yankho ndi lakuti: osati kwenikweni.Kusintha kwapangidwe kumatha kupititsa patsogolo kusungidwa kwa PCB.Ngati bulaketi yogulitsira, dzenje (microhole) la pini yokwera pamwamba, ndi pad lalikulu la soldering litayikidwa pamwamba, mphamvu yogwirizira imatha kuwongolera.M'malo mwake, ngakhale zolumikizira za I/O zimatha kugwiritsa ntchito zikhomo zapamtunda.Izi zitha kufananizidwa bwino ndi "kuyika mizu".Mwachitsanzo, pakupanga makina a X-ray, makina ojambulira akupanga, ndi ma switch a robotic Ethernet.
Chachitatu: Mapangidwe amphamvu.Kuti mudziwe kudalirika kwa cholumikizira, ndikulola kugwiritsa ntchito zida zopangira crimping, mbale yamtengo imayikidwa pa chipolopolo kuti ikhale yolimba, kuti ikwaniritse bwino kupanga ndikuwonjezera zotulutsa.Kunena mwachidule m’mawu amodzi ndi “olimba ngati thanthwe.”Ntchito zapadera monga positron emission tomography scanner, makina ophatikizira magalimoto a njanji, etc.
Chachinayi: mawonekedwe apamwamba, malo ochepa.Ndi miniaturization yamagetsi yamagalimoto ndi zamagetsi ogula, lingaliro lapangidwe la malo apano ndi ang'onoang'ono liyenera kuganiziridwa.
Chachisanu: Palibe kapangidwe ka pini yopindika pakupanga msonkhano.Kupondaponda kwachikhalidwe kumayambitsa kupindika kapena kupunduka kwa zikhomo chifukwa cha kukonzedwa kosayenera, ndipo kupindika kumayambitsa ming'alu ya capillary, yomwe siili yofunikira pakupanga kwanthawi yayitali, komanso kukhudza magwiridwe antchito ndi mtengo.Ndipo ERNI imagwiritsa ntchito kupondaponda pamakona, zopondapo zimatha kupewa ming'alu ya capillary yomwe imayambitsidwa ndi njira yopindika, ndikuonetsetsa kuti pali kulumikizana kwathunthu kwa electromechanical.Pin coplanarity ndi 100%, ndipo kulolerana kumayendetsedwa mpaka ± 0.05mm.Mayeso a 100% pamwamba pa pin pin coplanarity amatsimikizira kudalirika kwa ndondomeko ya msonkhano wa dera, amaonetsetsa kuti akugulitsidwa bwino, amawongolera mtengo wamtengo wapatali, komanso amachepetsa mtengo.Ndipo konzani kulimba kwa cholumikizira cholowera kumanja kuti cholumikizira chisawonongeke chifukwa chogwira ntchito molakwika.Mawu akuti "osasweka" ndi oyenera kwambiri.Ndizoyenera makamaka mawonekedwe a InterfaceModule module ya chowongolera chosindikizira cha inkjet.
Chachisanu ndi chimodzi: Mapangidwe apamwamba a loko.ERNI imagwiritsa ntchito zokhoma ziwiri kuti ikwaniritse zosowa zosiyanasiyana.Chotsekera chabwino chidapangidwa kuti chizigwira ntchito zogwedezeka mwamphamvu.Ndizoyenera kwambiri pamagalimoto agalimoto ndi metro.Chotsekera cha friction chidapangidwa kuti chizigwiritsidwa ntchito pafupipafupi.Maloko awiri ndi inshuwaransi yotetezedwa kawiri imatsimikizira kulumikizana kodalirika, ndipo palibe zida zapadera zomwe zimafunikira pakuchotsa (kukonza/kusintha) zingwe.Oyenera mapangidwe oyang'anira, magetsi LED galimoto, etc.
Zolumikizira za board-to-board zimagwira ntchito yofunika kwambiri pakupanga dongosolo lonse lamagetsi.Posankha zida zamagetsi, mainjiniya amayenera kusamala osati ukadaulo wa chip okha, komanso kusankha zida zotumphukira, kuti dongosolo liziyenda bwino., Sewerani zochulukira.
